“…However, due to technical complexity, radiation exposure and cost, DXA is not feasible for routine analysis. Bioelectrical impedance (BIA), which is definitely simpler and cheaper than DXA, is considered adequate to analyse body composition in normal subjects and in patients affected by different chronic diseases (Lukaski et al 1986, Chertow et al 1995, Cooper et al 2000, Ben Halim et al 2007. In MHD patients, the reliability of single (sf-BIA) versus multifrequency (mf-BIA) is still debated.…”

The aim of this study was to evaluate the adequacy of single-frequency (sf-BIA) and multi-frequency bioelectrical impedance analyses (mf-BIA), in comparison with dual-energy x-ray absorptiometry (DXA), to evaluate body composition in maintenance haemodialysis (MHD) patients. Body composition of 27 adult MHD patients (9 f, 18 m), BMI 17.5-34.4 kg m(-2), was examined with DXA and BIA, with two different sf-BIA and 1 mf-BIA analysers. Biochemical markers of nutritional status and adequacy of dialytic treatment were also determined. Fat mass (FM) estimated by the different BIA analysers was found to be slightly but significantly higher than FM measured by DXA. In contrast, fat-free mass (FFM) obtained with BIA was found to be slightly but significantly lower than FFM DXA. No significant differences were found between LBM-DXA (that is FFM-DXA minus bone mass) and the different FFM BIA. The lowest mean prediction error versus DXA values was found with sf1BIA. In any case, a close correlation was found between all BIA values and DXA values, particularly for FFM. Furthermore, FFM and LBM results were significantly correlated with serum creatinine, which in MHD patients is an indicator of muscle mass. These results indicate that BIA can be used to evaluate body composition in MHD patients.
